We select 3 balls without replacement from a urn containing 4 red balls, 3 yellow balls and 3 blue balls. Assuming equally likely outcomes, find the probability that we do not see all three colors in the three selected balls. Simplify your answer to a fraction a b .

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

the anwser is x< -17/2

10 times 13 = 130

10 times 13 = 130

130 + 130 = 260

if this you out can you make this answer the brainliest?
